A bearing system includes an inner ring that surrounds an axis of rotation, an outer ring spaced radially outwards from the inner ring, and a cage that is positioned between the inner and outer rings to support a plurality of bearing elements. The inner ring includes an axial slot that extends in a direction along the axis of rotation. The inner ring also includes at least one radial side slot formed in at least one of a fore and aft end surface of the inner ring. The radial side slot directs lubricating fluid from the axial slot toward the cage to lubricate the plurality of bearing elements.
